hello, I need some help on directions, I've been playing with my plugins on my locally host server normally for the past few weeks, but then suddenly when I log into my game today I found this warning message saying:

"In order to load plug-ins you need to add "-insecure" to the launch options"

Then when I tried to host a local game, all the plugins are disabled! Can anybody tell me how to fix this problem, I have no clue of where to look for the L4D2 launch option and to implement what the warning message have stated.
